Freelancer Overview

I am an experienced AI reviewer and QA specialist with over three years of hands-on work evaluating LLM-based systems and AI-driven solutions. My background includes extensive rubric-based grading, comparative response analysis, and detailed annotation of AI outputs to assess instruction adherence, logical consistency, and data reliability. I have contributed to the development and validation of AI models by identifying hallucinations, unsupported claims, and inconsistencies, as well as providing structured feedback to improve model performance. My work spans testing live AI systems in real-world scenarios, stress-testing trading bots, and analyzing data tools, all while ensuring outputs meet strict KPIs and quality standards. I am skilled in technical documentation, basic data analysis with Excel and Google Sheets, and have a strong foundation in analytical writing and structured communication, supported by certifications in data analytics and SQL.
